Thanks @Whitney168
One of the previews I read gives a tiny bit of detail
Cathie is 49 and runs two pharmacies with her husband She's been friends with 48 year old Tricia since they were 13. It's Tricia who's partially sighted, she has a new job since the adventure. The blurb says she was a bank clerk, but I'm sure I heard someone was a compliance officer, so presume that was her role, she's changed fields now though
Claudia is 27 and her dad, Kevin, 53 is Taxi Man. They're from Southampton. She's a product developer and buyer and he's a marine canopy maker
Ladi, 52 and Monique, 25 are father and daughter. She lives in East London working in events management and he's in Essex where he's involved in the sports and physical activities industry. Very close in age to Claudia and Kevin
Marc, 36 is a lift operator and his brother Michael, 34, is a children's services manager. Both of them are in the West Midlands
Zainib is a 32 year old psychiatrist from Glasgow and is married to 31 year old Mobeen from Manchester and he's a junior registrar trauma orthopedic surgeon
I like how you see the various strategies and approach to problem solving and how the relationships are affected by all their activities over the course of the race. Ladi's work skills have definitely helped with his can-do and crack on attitude so far. Let's hope it rubs off a bit on his daughter.
